Preliminary information
This guide is designed to provide the ost co plete infor ation the operator needs to correctly and
safely install and operate the LD220 touch-screen indicator series.
LD220 touch-screen indicator is designed to interface SSI encoders.
It accepts signals fro single- and ultiturn encoders with SSI interface, resolution in the range 10 to
32 bits and clock frequency up to 1 MHz. Operation can be as either Master or Slave. The features include
scaling, bit blanking, linearization over 24 interpolation points, choice of the engineering unit, sa pling
ti e setting, three HTL PNP control inputs (for exa ple for resetting the display value), etc.
It features a touch screen and 7-seg ent graphic display with a co plete set of plain text, sy bols and
units. The LED display is bright and provides high contrast readability and also allows the background
light to turn red, green or yellow in the event of the set occurrences such as when the threshold li its
are exceeded. The co bination of plain text and touch screen functions ake the para etrization very
user-friendly and intuitive.
In the series the following odels are available:
•LD220-P8 touch-screen indicator standard version;
•LD220-PM provides additional 115-230Vac power supply;
•LD220-...-AVI provides additional 16-bit analogue output, four control outputs and RS-232/RS-
485 serial interface;
•LD220-...-DO further offers four control outputs and RS-232/RS-485 serial interface;
•LD220-...-RO is equipped with two relay outputs.
All options (-PM-, -AVI-, -DO-, -RO) can be freely co bined.
For technical specifications please refer to the product datasheet.
To ake it easier to read the text, this guide can be divided into two ain sections.
In the first section (fro section 1 to section 4) general infor ation concerning the safety, the
echanical installation and the electrical connection.
In the second section (fro section 5 to section 8) both general and specific infor ation is given on the
operator enu and the setup procedure.
Operational modes
All functions can be configured in the para eter enu.
The device can be set to one of the following operation odes:
•MASTER, see the Mode para eter in the “6.3 SSI properties enu” section on page 41.
◦The unit provides the clock signal for the connected device.
◦Both clock ter inal blocks “5 – CLK” and “6 - /CLK” are configured as outputs.

•SLAVE, see the Mode para eter in the “6.3 SSI properties enu” section on page 41.
◦An external device (i.e. the SSI Master) ust provide the clock signal for the connected
encoder / sensor.
◦Both clock ter inal blocks “5 – CLK” and “6 - /CLK” are configured as inputs.

The device is allowed to be installed and operated only within the per issible
te perature range (-20°C +60°C / -4°F +140°F). Please ensure an adequate
ventilation and avoid any direct contact between the device and gases / liquids.
Before installation or aintenance, the unit ust be disconnected fro all
voltage sources. Further ore it ust be ensured that no danger can arise in the
event of contact with the disconnected voltage sources.
Devices which are supplied by AC voltages ust be connected only by eans of
switches or circuit breakers with low voltage circuit. The switch or circuit
breaker ust be installed as near as possible to the device and further indicated
as separator.
Inco ing as well as outgoing wires and wires for extra low voltages (ELV) ust
be separated fro dangerous electrical cables (SELV circuits) by using double or
increased insulation.
All selected wires and insulations ust co ply with the provided voltage and
te perature ranges. Further ore all country and application specific standards
which are relevant for structure, for and quality of the wires ust be ensured.
Indications about the per issible wire cross sections for wiring are described in
the product datasheet.
Before starting the unit for the first ti e it ust be ensured that all connections
and wires are fir ly plugged in and secured to the screw ter inal blocks. All
ter inal blocks (including unused ones) ust be fastened by turning the
relevant screws clockwise up to the end position.
Overvoltages at the connections ust be li ited to values in accordance with
the overvoltage category II.
For place ent, wiring, environ ental conditions as well as shielding and
earthing/grounding of the supply lines you ust co ply with the general
standards stated for industrial auto ation industry and the specific shielding
instructions provided by the anufacturer.
